The Doctor believed in giving people second chances. And people who were not, strictly speaking, people at all got one or two more than the real ones. And sometimes, if they were really honest, and truly needed it, people would get more second chances than other people thought they deserved.

The people who did that sort of thinking didn't get more than one second chance. If they were lucky enough to get one in the first place.

The survivors of the current disaster were Tracy, Blix, and Killbot 77. According to the crew who had died, the robot had been left running too long and had started to get a personality. Killbot 77 should have been recycled years ago, but the company was too cheap to get an upgrade.

Tracy got a second chance because she was kind to Killbot 77. Blix, because she had been trying to campaign against the recycling program for her entire career as Maintenance and Repairs.

But it had been a long run from the invading insects, the organics were tired and hungry and they were getting tetchy and arguing. And it didn't help that Killbot 77 was trying to be helpful. The poor thing just wound up being trying.

"It is past your regular power-down cycle," said the robot. "You have missed two sustenance periods. In an effort to continue maintenance, I have found and secured... supplies."

It was an honest effort. Killbot 77 had acknowledged that organics needed certain elements in order to sustain their bodies and secured a scientific portion of them. Unfortunately for Killbot 77, they had yet to learn about edibility.

The Doctor looked at the collection of soap, nuts, bolts, plant fibre and assorted chemicals and sighed, "The theory's correct, but the practice needs a lot of work."
